We had 2 nest teams. Team A did all but the second bottom nest, Team B did only the second bottom nest.
Team A: 2x Lock, Shadow Priest
Team B: Mage, Hunter, Enh Shaman
Additionally, our disc priest went for a feather now and then, and our guardian tank tanked the adds.
We had all our DPS use personal survival CDs + Healthstone if needed to survive Quills without a healer. If you do it correctly you don't take any other damage really when down there, so no need to send a healer down.

Team B used their feathers to catch nutriments for the DPS boost. When everything was down on the second platform we waited for Ji Kun to cast Caw before flying back; about 5 seconds after Caw he starts throwing the nutriments, so we could grab those with the feather we flew up with.
If one of your Team B DPS has short cooldowns (1.5 min tops), you can save a feather to catch a nutriment later to get more out of your cooldowns. (As a mage, I save 1 feather to do a second combustion with my 3 feathers).

The second round of nests, you get a double spawn. After Team B did their bottom nest you get one nest down and one nest up. Team A would get the down nest, Team B would use a feather straight away after killing the adds to fly back to the platform, then use a new feather when they can to get to the top nest. After Team A finishes up the nests on top we'd blow BL and just burn him down.

To sum up and answer your questions:
- Double nest spawn (9th and 10th spawn at the same time)
- The supplementary add doesn't _need_ a tank, but it does help. As long as you can kill it fast enough your nest tank should be up in time again to take the boss.
- The enrage isn't tight at all if your DPS does well with their buffs. As long as you keep up with nests you're most likely good to go.

Thanks very much, the info is appreciated. And there are many guilds working their way to this in the next couple weeks so IT IS timely. In fact I wish there were a lot more of these "how to heroic boss" threads. So thank you.

there are less than 50 guilds on wow progress that have gotten that far into ToT..why do i feel this is little more than bragging?

You don't have to progress linearly in heroics. HJK is supposedly one of the easier ones. I don't think he's bragging, my guild is attempting it this week and we're only 1/12 H, based on advice from other heroic raider guilds on our server.

Ryoushi your post was awesome. I'll be relaying the info to my guild this week as well for our attempts. Thanks!
